375 Orbital Element Sets v3.04done

Up to 200 repetitions of Orbital Element.

Holds the orbital elements for some sattelites.

Description

The GUI suggests, that up to 200 entries can be written, however, for now the CPS writes a fixed size of 1600h, corresponding to 11 elements.

376 Orbital Element v3.04done

Element of size 200h.

Holds the (TLE) orbital elements for a single sat.
